Welp, I've never been on an Amtrak with a Viewliner, so my mistake, but I've ridden the Amtrak many times and have never seen that particular style of railcar. They've always been two-story, and apparently that's a one-story railcar (presumably why they need to economize space like that).

Wikipedia says that they're primarily used on the east coast, so that's probably why I've not seen one. I've ridden all over the lines west of Chicago. I'd love to do their new Chicago to Miami line sometime, so perhaps I'll have the privilege.
